Analysis of Fire Line Vibration and Realization on Motion Prediction Gate

Abstract

During the dynamic firing process of artillery of armored vehicle, the fire line cannot stay in the firing door stably due to the influence of vehicle vibration and road excitation. Through the analysis of the firing line vibration in the firing process of the weapon station, it is found that the main frequency is concentrated below 10Hz, and the noise frequency is introduced from the start-up of the ammunition conveyor. After filtering the interference frequency, the 10-step prediction error is significantly reduced. Then the concept of "prediction gate" is proposed. Based on the original firing gate, the prediction value is used as the firing gate judgment condition, which not only reduces the shooting error, but also prolongs the controlled time of the fire line, and provides a new idea to solve this problem.
